Valdis Bojarevics

Professor Valdis Bojarevics PhD

Professor of Computational MHD

Professor Valdis Bojarevics is an internationally recognised specialist in the field of computational magneto-hydro-dynamics (MHD). He was born in 1952 Riga (Latvia), started his research career in 1975 at the Institute of Physics in Latvia -at that time the largest research centre specializing in various aspects of technological and astrophysical magnetohydrodynamics.

He became a specialist in developing original computational models for a wide range of practical applications and supporting physical experiments in the electro-metallurgical industry. Professor Bojarevics has been invited to several internationally leading research centers for collaborative work:1991and1992 Ecole Federale de Lausanne (Switzerland), 1993 MADYLAM laboratory, Grenoble (France), 1993-1995 Reynolds Metals Research Centre (Alabama, USA. In 1995 Professor Bojarevics was invited to join the Computational modelling group at the University of Greenwich. At Greenwich Professor Bojarevics has been involved in industrial collaboration with a number of commercial companies (Reynolds Metals Company, Alcoa, Noranda, Rolls Royce, Howmet, Qinetic, China Aluminium, Dubai Aluminium, Corus, Special Metals, Consarc).

In 2001 Japan Society for the Promotion of Science (JSPS) invited Professor Bojarevics for the research fellowship in Japan, Tohoku university. He presents talks regularly at the most important international meetings of research communities in liquid metal MHD, EPM and light metal processing. His track record also includes successful participation as Co-investigator in a number of EPSRC (GR/L97483/01, GR/N14316/01, EP/D505011/1), DTI Technology Programme (Q1536D) and international collaborative projects (EU ALEL, EU IMPRESS, ESA MAGLEV, EU COST-Magnetic-fluid-dynamics).

Professor Bojarevics contributed to the development of the Masters Programme with the originally created course 'Electrodynamics with Matlab', supervises MSc student projects and PhD students.
